Dynamic configuration (recommended)
If you configure your Netopia R2121 using SmartStart, you can accept the dynamic IP address assigned by your
router. The Dynamic Host Configuration Protocol (DHCP) server, which enables dynamic addressing, is enabled
by default in the router. If your PC is not set for dynamic addressing, SmartStart will offer to do this for you
when you launch it. In that case, you will have to restart your PC and relaunch SmartStart. If you configure your
PC for dynamic addressing in advance, SmartStart need only be launched once. To configure your PC for
dynamic addressing do the following:
Note: You can also use these instructions to configure other computers on your network to accept IP addresses
served by the Netopia R2121.

3. Click on the DNS Configuration tab. Click Disable DNS.
DNS will be assigned by the router with DHCP.
